BOMB DBOPPER FOR AEROPLANES.

Application filed August 18, 1926. Serial No. 129,984.

This invention relates to bomb droppers I for aeroplanes, and has forits object to provide an improved means for dropping bombs in successionfrom aeroplanes or the like, said means being under the control of anoperator in the aeroplane.

The invention is illustrated in the accompanying drawing which is alongitudinal sectional view of the mechanism.

This mechanism may be attached to the bottom or any other suitable partof the aeroplane being in position for operation, and it includes upperand lower guide plates and 6 conveniently attached to a wall 9, theguide walls being slotted as indicated at 7 and 8. A bomb hopper 10 ispositioned over an opening 11 in plate 5. A plunger 12 works back andforth between the guide plates and has a slotted rear discharging end asindicated at 13. The opposite ends of plates 14 and 15 are securedthereto and behind the plates are notches 16 and 17. A recess 18 in theend receives a coiled spring 19 mounted on a post 20 projecting from abracket 21 provided with a head 22 fixed to the wall 9. A shaft 23pivoted to the side of the head has an operating lever 24 carrying sidelevers 25 the arms of which are pivoted to pawl bars 24 and 25 thehooked ends 24 and 25 of which work in 24 is thrown backwardly and thehook 25 of bar 25 engages the notch 17, drawing the plunger forwardlyand compressing the spring19. As the slot 13 passes under the opening11, one of the bombs 28 drops therein. As the bar 25 slides forwardly,

it engages the head 22 and is thrown outof the notch, thereby releasingthe plunger 12 which is projected rearwardly by the spring 19 and thebomb is thrown out of the slot 13. To discharge the next bomb, the lever24 is pushed forwardly with'the hook 24 then in engagement with thenotch 17. This draws the plunger 12 forwardly and another bomb dropsinto slot 13, and as the movement continues, the bar 24 rides over thehead 22 and releases the hook 24 from the notch and the plunger 12 thensprings backwardly to discharge the bomb. The operation may thus berepeated. The spring 19 is preferably so constructed as to discharge,the bomb r-earwardly at about the same rate of speed at which theaeroplane is flying forwardly, so that the bomb may be releasedperpendicularly with approximate accuracy.

I claimr 1. A bomb dropper comprising a bomb hopper, and a springpressed plunger working under the same, a lever, a pair of springpressed pawl bars connected to the lever and alternately engageable withopposite sides of the plungerto advance the same and compress itsspring, and means to release the pawl bars from the plunger, to permitthe spring to return the plunger and discharge the bomb. I

2. A bomb dropper comprising a pair of upper and lower slotted guideplates, a plunger slidable between the plates and having notchesregistering with said slots, means to feed bombs into position'betweensaid plates and behind the plunger, a spring pressing against the frontend of the plunger, an operating lever, a pair of pawl bars pivoted tosaid lever and working in said slots and adapted to successively engagein the notches in the plunger and move the plunger forwardly, and meansto disengage the pawl bars respectively from the notches at the limit ofsaid forward movement.

In testimony whereof, I do affix my signature.

ANTON NOSAN.
